摘要
Abstract
Aiming at the problems of increasing additional hardware overhead and sacrificing loading speed in the existing embedded OS loading mode selection method,an embedded OS loading mode selection method based on link state information is proposed.The method utilizes the reset of PHY and other peripherals after power-on and then reset the CPU,which runs the BootLoader to read and judge the link establishment signal of PHY to determine the loading mode,and if the link establishment signal indicates that the network has been connected,the Ethernet remote loading mode will be selected,while the local memory loading mode will be selected in all other cases.The results of engineering application show that the proposed method is stable and reliable.关键词
